Background and Purpose-Stroke incidence rates are in flux worldwide because of evolving risk factor prevalence, risk factor control, and population aging. Adelaide Stroke Incidence Study was performed to determine the incidence of strokes and stroke subtypes in a relatively elderly population of 148 000 people in the Western suburbs of Adelaide. Methods-All suspected strokes were identified and assessed in a 12-month period from 2009 to 2010. Standard definitions for stroke and stroke fatality were used. Ischemic stroke pathogenesis was classified by the Trial of ORG 10172 in Acute Stroke Treatment criteria. Results-There were 318 stroke events recorded in 301 individuals; 238 (75%) were first-in-lifetime events. Crude incidence rates for first-ever strokes were 161 per 100 000 per year overall (95% confidence interval [CI], 141-183), 176 for men (95% CI, 147-201), and 146 for women (95% CI, 120-176). Adjusted to the world population rates were 76 overall (95% CI, 59-94), 91 for men (95% CI, 73-112), and 61 for women (95% CI, 47-78). The 28-day case fatality rate for firstever stroke was 19% (95% CI, 14-24); the majority were ischemic (84% [95% CI, 78-88]). Intracerebral hemorrhage comprised 11% (8-16), subarachnoid hemorrhage 3% (1-6), and 3% (1-6) were undetermined. Of the 258 ischemic strokes, 42% (95% CI, 36-49) were of cardioembolic pathogenesis. Atrial fibrillation accounted for 36% of all ischemic strokes, of which 85% were inadequately anticoagulated. Conclusions-Stroke incidence in

“…In two recent population-based studies focused on a predominantly White population, a high incidence of the LAA subtype was reported, which might be related to the stroke pathophysiology classification system used, distinct of the classic TOAST classification 5,8 . In our study, the incidence observed could be explained by the prevalence of risk factors and possibly genetic susceptibility, because most of the Brazilian population has some amount of African genomic ancestry, and it is recognized that ethnicity is an important contributor to atherosclerotic risk factors 3,6,7,27,28 .…”

Previous population-based studies reported the incidence and mortality of ischemic stroke (IS) subtypes in different settings, most of them on the White population from high-income countries 1,2,3,4,5,6,7,8 . In Latin America, there is only one study, which was conducted in a Spanish and Mestizo population in Iquique, Chile 9. As far as we know, no previous study has reported IS subtypes rates among predominantly White people from Latin America.The crude annual incidence rate of IS in Brazil range from 62 to 92 per 100,000 inhabitants with a mixed pattern of cardiovascular risk, characterized by high prevalence of ischemic heart disease, dyslipidemia, hypertension and diabetes 10,11 . Determining the incidence, mortality and risk factors among IS subtypes may help to improve the public health actions and reduce the IS disease burden 12,13 . ABstrAct Aims: To measure the incidence and mortality rates of ischemic stroke (IS) subtypes in Joinville, Brazil. Methods: All first-ever IS patients that occurred in Joinville from January 2005 to December 2006 were identified. The IS subtypes were classified by the TOAST criteria, and the patients were followed-up for one year after IS onset. Results: The age-adjusted incidence per 100,000 inhabitants was 26 (17-39) for large-artery atherosclerosis (LAA), 17 (11-27) for cardioembolic (CE), 29 (20-41) for small vessel occlusion (SVO), 2 (0.6-7) for stroke of other determined etiology (OTH) and 30 (20-43) for stroke of undetermined etiology (UND). The 1-year mortality rate per 100,000 inhabitants was 5 (2-11) for LAA, 6 (3-13) for CE, 1 (0.1-6) for SVO, 0.2 (0-0.9) for OTH and 9 (4-17) for UND. Conclusion: In the population of Joinville, the incidences of IS subtypes were similar to those found in other populations. These findings highlight the importance of better detection and control of atherosclerotic risk factors.
